The device of this invention comprises mechanism by which the operationof an automatic phonograph of the juke box type, and the turning on andofi of a television receiver can be controlled from any of the coinreleased record selector devices by which the juke box itself isremotely controlled.

In such automatic phonographs, the records are supported in horizontaltrays arranged in a stack. The records are movable one at a time fromrest position within the stack to playing position above the turntableand then back to the stack. Movement of the records from the stack toplaying position is controlled by the coin released record selectordevices.

Starting the juke box on the playing of any one of the records withinthe stack is accomplished by inserting a coin into the coin slot of oneof the record selector devices and operating the selector key or buttonopposite the title of the chosen record.

These record selector devices are either part of the juke box itself orare located at stations or positions remote from the'juke box, and eachcomprises at least one coin slot and a series of selector keys orbuttons; one such key or button being employed for each record withinthe stack.

Wurlitzer phonograph model 1100 is a typical example of an automaticphonograph of the juke box type such as here contemplated, Suchphonograph is illustrated and described in more or less detail in TheRudolph Wurlitzer Companys book entitled Service Instruction PartsCatalog Part-No. 298-5.

Each such phonograph, beside having a stack of record trays mounted forswinging movement to and from such stack and each carrying a phonographrecord, has a turntable, a tone arm and its needle, and a tray takeoutmechanism arranged to swing one tray at a time (the tray of the selectedrecord) from rest position within the stack to position above suchturntable and then, when the needle of such tone arm reaches the end ofthe trip or runout groove of such record, to swing such tray back torest position within the stack. Operation of the tray takeout mechanismis indirectly controlled from the coin released record selectors.

Such a phonograph also includes an amplifier and a junction box fromwhich current is derived for the phonograph motor, the selector drum,the stepper, 'the sound system and other elements entering into themake-up of the phonograph or juke box. I

In carrying out the conjoint control of a television receiver and suchan automatic phonograph or juke box, I utilize one of the trays of thestack, the record carried by such tray, the tone arm: and its needle andthe tray takeout mechanism as part of the means for determining thelength of each playing period of the television receiver. Part at leastof the playing time of the television receiver, therefore, depends uponthe length of therecord groove and since this record (the recordselectedfor the television control) is played silently, that is, with theamplifiercut ofi, it can have a plain, smooth groove which can extendnearly to the end of the trip or runout groove if desired in order tolengthen the playing time of the television receiver.

Since the movement of any tray toward the stack after its record hasbeen played does not begin until the needle of the tone arm reaches theend of the trip or runout groove of such record, the record selected asthe television control record becomes a vital part of the mechanism forcontrolling the playing time period of the television receiver.

This record as above pointed out can either be an ordinary phonographrecord such as used in the stack or a special record with a plain smoothgroove of the same or greater length than that of the ordinary record,as long as it has a trip or runout groove for moving the tone arm to thecenter of the rec- 0rd.

The record, of whichever type, used in the timing of the televisionreceiver playing period is played silently since the amplifier is turnedoif during such playing. Movement of the record tray from rest positionin the stack, or movement of part of the mechanism associated with suchtray movement is utilized in the operation of a switch for turning offthe amplifier and turning on the television receiver.

In cases where it is desired to prolong the playing period of thetelevision receiver for a materially longer time than it takes theneedle of the tone arm to traverse the groove of the record, instead ofusing a special record with an abnormally longer groove, I prefer tostop the record tray on its way back to rest position within the stack,and I do this by cutting off the current to the phonograph motor for acertain period of time. When this period of time expires, the current tothe phonograph motor is again turned on and the record trayproceeds onits way to rest position within the stack.

Since the invention of this application does not change or modify theoperation of any of the parts entering into the'make-up of the automaticphonograph or juke box, only portions of such mechanism are referred toor illustrated. The parts that are referred to as well as the televisionreceiver are merely shown diagrammatical- 1y.

The stack of trays with the records therein is numbered l5, the 7turntable 16, the coin released record selector (wall box) I1, thejunction box l8, the amplifier Hi, the television receiver 20, thephonograph motor 2!, the tone arm 22 and the record takeout mechanism isnumbered 23 as an entirety.

For the television receiver playing time con trol record, I prefer toutilize the topmost record in the stack which is immediately below thestack cover 24 and as above pointed out, such record can be a regularphonograph record such as the others in the stacker it can be a specialrecord with a plain, smooth groove of any length, short or abnormallylong, but must terminate in a trip or runout groove.

Since it is desirable to be able to control the duration of the playingtime period of the television receiver to suit difierent conditions, Iprefer to use an ordinary phonograph record as the control record and tointerrupt travel of the tray of such record from playing position backto rest position within the stack, and to provide means by which theduration of such interruption can be varied or adjusted. i

7 Movement ofthe record trays from rest position within the stack toposition above the turntable 'is'accomplished by the record'tray'takeout mechanism. This position above the turntable becomesplaying position when the turntable in its upward movement through therecord tray .picks up the record and raises it to playing positionasshown in Fig. l where record 25 has been lifted. from its tray 26 byturntable I6. Movement of the tray takeout mechanism 23 for returning atray and its record to rest position .within the. stack is initiatedwhen the needle of ;the tone arm reaches the end of the trip or run-.out groove of. the record, causing thetone arm atomove. to the centerof the record.

. In the preferred embodimentof my invention, 11- provide a switchdevice which is operated to out off the amplifier l9 and turn on thetelevision receiver 20 when the recordztray takeoutmechavnism 23 reachesthe position for taking out tray .26 of record .25, the topmost recordof thestack. Such switch device is numbered 21 and is. provided with acenter prong 28 and side prongs .29 and 30. These prongs are providedwith terminal members as disclosed in Figs. 3 and 4 and normally centerprong 28 contacts with side prong 29,, the amplifier side prong, so.that. the amplifier is normally turned on when the motor of thephonograph or juke box is running.

Center prong 23 projects beyond the side prongs and into the path of.movement ofpart 3| of the tray takeout mechanism so that when .such partinmoving up from the position shown in Fig. 3

-reaches-the. position shown in Fig. 4, prong 28 is separated from prong29, and contacts with side prong 30., thus disconnecting the amplifierand connecting or turning on television receiver 26. Since the topsurface of part 3| of the tray takeout mechanism is smooth and flat,contact prong 28"Will' remain "in contact with television prong "3'0 andout of contact with amplifier prong 23 as long as part 3| remains in theposition shown in Fig. 4. This position represents the upper limit oftravel of part 3| and therefore the upper limit "of the tray takeoutmechanism which includes part 3 I.

Tray takeout mechanism '23 is swung about vertical support post 32 andis moved up and :down

alongsuch post in order to be in position to take out the different:trays constituting stack l5.

In order to interrupt or stop travel of tray 26 with its record 25during its travel from playing position (the position of Fig. 1) back torest position within the stack, I utilize a switch device 33. Thisswitch device comprises two normally separated prongs 34 and 35 whichare located in the circuit of a solenoid 36 (Figs. 1, 10 and 11) used toactuate a timing device 31 (Figs. 1 and 4) which is here shown as aspring operated clock mechanism 38 (Figs. 10, 11 and 12) arranged toopen a normally closed switch 39 -(Figs. 10 and 11) located in thecircuit of the .motor 2| of the phonograph or juke box, stoppingoperation of such'motor and therefore the tray takeout mechanism, untilsuch clock mechanism runs down, again cutting in such motor;

tray 26 and record 25 then completing their travel tion;z playingposition to rest position within the s ac Solenoid 36 under the controlof switch device 33 is plugged into an A. C. power circuit by means ofterminal plug 40. Switch device 33 is operated by a blade-like agent 4|which is preferably bolted to and carried by part 42 which movesvertically with part 3| of the tray takeout mechanism and is swung aboutpost 32 during the operation of such takeout mechanism. During .-.m.0 emnt Ofatray. from .rest position within the 6 the stack to position abovethe turntable, the tray takeout mechanism is swung counterclockwise andduring movement of such tray-and record back to rest position within.the stack, such mechanism is swung clockwise.

Agent 4| is provided with a prong contact portion 43 which is so bentfrom the horizontal. that in moving counterclockwise between the prongs,it will depress prong 35, overseparating the prongs. During itsclockwise movement, when the tray and its record is traveling back torest position withinthe stack, prong contact portion 43 will force prong35 into contact with prong 34, thus closing the solenoid -circuit,..andenergizing the solenoid.

These movements of agent 4| are-depicted in side and end elevation inFigs; 5-9 inclusive and in top. plan in Fig. 2. In this view, theoutline of the record tray in position above-the turntable is shown bydot and dash line 44 and the position at which travel of the tray andrecord back to rest position is interrupted is indicated -'-by dot anddash line 45.

Solenoid 36 is provided with a movable'plunger 46 which has its movementinto the 'solenoidcoils limited by a screw "which is threaded throughthe base plate 48-of the solenoid. Plunger 46 at its center has a boreas indicated by dotted line 49 to receivea spring 56 which bears againstthe inner end of screw 4'! and tends to hold plunger 46.away from suchscrew.

The outer end of plunger 46 is slotted as at 5| to receive the end of alever 52 which is pivoted at 53 and has its end opposite slot 5|arranged in line with a lever 54 by means of which the spring of theclock mechanism iswound. Lever 54 is secured to the squared end 55 ofthe shaft which carries gear wheel 56. The balance wheel is numbered 51.

The clock mechanism is such that it is normally run down or unwound. Atsuch time, switch device 39 is closed as shown in Fig. 10 and thecircuit of the phonograph motor therefore is also closed so far asswitch device 39 is concerned.

When switch device 33 is operated to energize the solenoid and openswitch 39, the phonograph motor is stopped and movement of tray '26 andits record 25 from playing position to rest position within the stack isinterrupted and such interruption continues until the clock mechanismruns down and switch 39 .is .again closed.

As soon as switch device 33 is closed,.the solenoid through levers '52and 54 winds the clock mechanism. The operation of switch device 33 issubstantially instantaneous and spring 50 immediately restores thesolenoid plunger 46 and lever 52 to the position shown in Fig. 10,leaving lever 54 in the position shown in Fig. 11. Screw 41 is used asan adjustment screw for limiting the inward movement of the solenoidplunger and by limiting the movement of the spring winding lever 54 itcontrols the degree to which spring 58 is wound.

With the winding of spring 58, switch 39 in 'the motor circuit is openedby lever 59 as shown of-those (wall boxes) remote fromsuch phonoaphoutmechanism, is operated by one of the trays,

and its record included in stack l5, preferably the topmost tray. Centerprong 28 of switch 21 carries a'relatively thin tray contact member 61.Switch 27 is so supported from some suitable part of thejuke box chassisthat prong 28 is normally held in contactwith amplifier prong 29 by tray26 when such tray is in rest position within the stack as shown-in Figs.13 and 15. In Fig. 13, contact member 61 is shown contacting with thatportion of the peripheral edge of tray 26 which travels the greatestdistance when moving from rest position within the stack (the positionshown in full lines in this view) to position above the turntable, whichposition is shown by dot and dash lines.

out of rest position, prong 28 follows the tray and moves into contactwith television side prong 30. This is possible because of theblade-like character of contact member 6! (Figs. 15 and 16).

In.Fig. 14, tray 26 is moving from rest position (shown by dot and dashlines) to position above the turntable. With this arrangement, as

soon as the topmost tray 26 moves a sufficientdistance .on its way toposition above the turntable to permit center prong 28 to assume normalposition, such prong breaks contact with the amplifier side prong 29 andmakes contact with side prong 30, thus turning on or connecting thetelevision receiver. With this construction, the television receiverWill rem'ainconnected or turned on untiltray 26 again reaches restposition withm the stack and moves center prong 28 out of contact withthe television side prong 36.

If record 25 is a standard record, such as now used in juke boxes withthe turntable rotating at about 78 R. P. M., the playing time period ofthe television receiver will correspond to the playing time of suchrecord and probably will be too short. As above pointed out, however, aspecial record having an abnormally long groove may be used as the timerfor the television receiver playing time. 1 It will also be apparentthat the travel of tray 26 with its record 25 from position above theturntable to rest position within the stack can be interrupted in thesame manner and by the same means employed in connection with the layoutof Figs. 1-12 inclusive If the scheme depicted in Figs. 13-16 inclusiveis utilized as the solemeans for timing the television receiver playingtime period, there will be an interruption in the operation of suchreceiver each time the record reaches rest position within the stack,even if a propercoin is deposited before the television time expires,because the record tray 26 in moving into rest position disconnectsprong 28'from television prong 30. This scherne therefore, is not asflexible and therefore not as satisfactory as the scheme depicted inFigs. 1-12 inclusive, even if a record is used having a groove of suchlength as to provide a television receiver playing time period of thedesired length. for the reason that if it is desired to prolong theperiod of depositing one or more coins of the proper denomination, therewill still be interruptions between the playing time periods.

This is so because the construction of most automatic phonographs of thejuke box type is such that if, during the playing of any certain record,another proper coin is deposited, the playing of such record will berepeated as long as another proper coin is deposited before the end ofeach playing period. At the end of the first and each succeeding playingperiod, however, such record and its tray will be swung back to restposition within the stack and then out to position above the turntablebefore repetition of the playing of such record begins.

During these movements of the tray to and from rest position; part 3| ofthe tray takeout mechanism (the instrumentalities by which the trays andrecords are moved from and to rest position within the stack) remains inthe position to which it was raised in response to the first operationof the key of the coin released record selector device (wall box). I

If the topmost record, the one used for timing the television'receptionperiod, is selected, part 3| will be raised to the upper limit of itstravel in response to the first operation of key 63 of any wall box andwill remain at such limit with the television receiverturned on as longas a coin-is deposited before the end of each silent playing of suchtopmost record 25. It will be apparent,

therefore, that the method and means depicted What I claim is:
